LM2931AD-5.0G

onsemi · Linear Voltage Regulators (LDO) · SOIC-8

LM2931AD-5.0G from onsemi, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Output power_out Regulated 5.0 V output supplying more than 100 mA, requiring an external output capacitor for stability (
2 GND power_in Ground pin, internally common with the other GND pins (pins 3, 6, 7).
3 GND power_in Ground pin, internally common with the other GND pins (pins 2, 6, 7).
4 N.C. unconnected No internal connection on the fixed-output SOIC-8 device.
5 N.C. unconnected No internal connection on the fixed-output SOIC-8 device.
6 GND power_in Ground pin, internally common with the other GND pins (pins 2, 3, 7).
7 GND power_in Ground pin, internally common with the other GND pins (pins 2, 3, 6).
8 Input power_in Supply input rated 40 Vdc continuous, 60 Vpk transient (load dump, ≤100 ms) and −50 Vpk reverse transient.
